The CAPM calculator can be used to calculate the cost of equity, to evaluate the investment effectiveness of collective investment funds (open-end investment funds, pension funds, etc.), to study the efficiency of the stock market, etc.
The CAPM model allows to illustrate the relationship between the incurred systematic risk, otherwise known as market or non-diversifiable risk, and the expected rate of return.

The CAPM calculator in the form of CML allows you to calculate the expected rate of return from the so-called the effective portfolio (on the border of Markowitz's effective portfolios).

With this calculator you will calculate the average absolute deviation, or mean absolute deviation (MAD), of a data set is the average of the absolute deviations from a central point.
